Peptides EU review: is Peptides EU legit? Documentation, policies and gaps

Our verdict

Peptides EU presents itself as an EU-fulfilled supplier of research-use-only peptides to laboratories. It names Janoshik Analytical as its testing laboratory, says purity is measured by reverse-phase HPLC and identity by mass spectrometry, and links certificates from product pages. [1] [4] [7]

The gaps are about identity and lot coverage. The terms call Peptides EU a trading name and storefront without naming the company behind it. The about page says "selected batches" are verified. The product page we checked showed no lot number in its text. [3] [6] [7]

We have not purchased from Peptides EU, inspected a vial against a certificate, or audited its operations. This review covers what can be checked from public pages and registries on 29 October 2026. Status: partly documented, not disproven.

Business identity

A UK office with EU fulfilment is not a contradiction in itself; many sellers use third-party warehouses. It does mean you should ask which entity issues your invoice and from which country the parcel ships, because both affect VAT and import treatment.

Certificates, laboratory and test methods

The FAQ names Janoshik Analytical and says purity is by reverse-phase HPLC and identity by mass spectrometry. The about page repeats both methods. [4] [6]

Coverage is the open question. The FAQ says "selected independent Certificates of Analysis" are published, the about page says "selected batches are verified", and the disclaimer says batch-specific certificates are provided "where applicable". None of these promises a third-party report for every lot. [4] [5] [6]

On the NAD+ product page we checked, the 100 mg item was listed while both certificate entries were titled for a 500 mg item, one for purity and one for sterility. Both carried the caption "Independent HPLC testing by Janoshik Analytical – Manufacturer's Report". A sterility result is not an HPLC result, so ask what each document is and which lot it covers. [7]

The FAQ also says researchers can send samples to an accredited independent laboratory for extra assurance. That is a reasonable step if the material matters to your results. [4]

Prices and payment

Prices are public and in euros. On the product page we checked, a 100 mg vial was €34.99, with automatic volume discounts of 5% at 3 vials, 10% at 5 and 15% at 10 (€29.74 per vial at 10). That item was out of stock on 29 October 2026. [7]

Accepted methods are Visa, Mastercard, SEPA bank transfer and Bitcoin; taxes and shipping are shown at checkout, and the order is confirmed only after payment clears. Returning customers are offered 5% off reorders. [1] [3]

Shipping, returns and claims

The claims clause that names a mismatch with the batch certificate is useful: it gives you a defined basis for a complaint, but only within 48 hours, which is shorter than most outside testing takes. [2] [3]

Regulatory and registry checks

FDA warning letters: a search of FDA's warning-letter list for "Peptides EU" on 29 October 2026 returned no letter addressed to Peptides EU or peptides-eu.net. FDA is a US regulator, so this check is of limited relevance for an EU-shipped seller. [8]

UK and EU regulators: we did not search MHRA or national EU authority enforcement records for this review. If your institution requires it, add that check and date it.

Company registry: without a legal entity name, a registry search cannot be anchored. Ask Peptides EU which company issues invoices, then search that exact name. [9]

A clean search is a dated observation, not a clearance. Our regulatory background check guide explains how to record it.

Pros and cons

Based only on the public pages above.

• Pro: names its testing laboratory and states HPLC and mass spectrometry. [4]
• Pro: public euro prices, volume tiers and a SEPA option. [1] [7]
• Pro: intra-EU shipping with stated customs and VAT position, and a lost-parcel replacement clause. [2] [3]
• Con: no legal entity named; UK office with EU fulfilment from an unnamed country. [2] [3]
• Con: only selected batches are said to be verified; no lot number on the product page text we read. [6] [7]
• Con: certificate captions on the product page are ambiguous about which document is which. [7]
• Con: no returns after dispatch, 48-hour claims window, and duties for non-EU destinations not assigned. [2] [3]

Gaps to close, and alternatives

• Ask which company issues the invoice, with its registration number and country.
• Ask for the certificate for the exact lot that will ship, with the Janoshik report or task number.
• Ask what the "Manufacturer's Report" caption means for each posted certificate.
• If you are outside the EU, ask in writing who pays duty and import VAT.
• Alternatives to compare on documentation: OMNI Peptides (US address, gated library) and Evolve Peptides (US, batch lookup). See our comparison guides.
• Supplier references are listed on our Tools page with an affiliate disclosure. Guides never carry affiliate links.
